Inert Ingredients No Longer Used in Pesticide Products

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: EPA is removing certain chemicals from its list of pesticide 
product inert ingredients that are not currently used in pesticide 
products. Future use of these chemicals as inert ingredients in 
pesticide products will not be permitted unless a petitioner or 
registrant satisfies all data requirements as identified by the Agency, 
and the Agency is able to make a determination that the use of the 
inert ingredient will not pose unreasonable risk to human health or the 
environment. All tolerances or exemptions from the requirement of a 
tolerance for the use of these chemicals as inert ingredients in food-
use pesticide formulations will be proposed for revocation at a later 
date in a separate Federal Register Notice.
DATES: This notice is effective on June 24, 1998. This notice is 
subject to revision if comments are received and revision is warranted. 
Comments must be received on or before August 24, 1998.
ADDRESSES: By mail, submit written comments to: Public Information and 
Records Integrity Branch, Information Resources and Services Division 
(7502C), Office of Pesticide Programs, Environmental Protection Agency, 
401 M St., SW., Washington, DC 20460. In person, deliver comments to: 
Rm. 119, CM #2, 1921 Jefferson Davis Highway, Arlington, VA.
    Comments and data may also be submitted electronically to: opp-

SUPPLEMENTARY INFORMATION: This notice announces those List 1, List 2 
and List 3 inert ingredients that are no longer used in pesticide 
products.

I. Background

    On April 22, 1987, EPA announced certain policies designed to 
reduce the potential for adverse effects from the use of pesticide 
products containing toxic inert ingredients (52 FR 13305). In 
developing the policy, the Agency reviewed the available data on 
chemicals used as inert ingredients, and concluded that some inert 
ingredients had potentially significant long-term health and 
environmental hazards

[[Page 34385]]

associated with their use in pesticide products.
    The 1987 notice categorized all inert ingredients into four lists, 
according to toxicity, as follows: List 1 inert ingredients, described 
as ``inerts of toxicological concern,'' were so categorized on the 
basis of toxicological or adverse ecological effects which had been 
documented in studies subject to peer review. List 2 inert ingredients, 
``potentially toxic inerts/high priority for testing,'' are 
structurally similar to chemicals known to be toxic and may have data 
suggesting a basis for concern. List 3 inert ingredients, ``inerts of 
unknown toxicity,'' do not have data supporting their inclusion on 
Lists 1 or 2 (or 4; see below). List 4 inert ingredinets, ``minimal 
hazard or risk inerts,'' consists of ingredients which are generally 
regarded as innocuous.
    In a susubsequent Federal Register notice, EPA further revised List 
4, creating two subcategories: (1) List 4A, ``inerts generally regarded 
as safe'' and (2) List 4B, ``inerts for which EPA has sufficient 
information to reasonably conclude that the current use pattern in 
pesticide products will not adversely affect public health or the 
environment'' (54 FR 48314, November 22, 1989). The Agency further 
revised List 4A in 1994 (59 FR 49400, September 28, 1994)(FRL-4872-5), 
and continues to evaluate the toxicity of inert ingredients. EPA's 
designation of inert ingredients according to list has been published 
as the ``List of Pesticide Product Inert Ingredients'' ( May 17, 1995), 
and is available through the Office of Pesticide Program's Public 
Information and Record Integrity Branch at the address given above.
    The criteria used for placement of inert ingredients on List 1 were 
discussed in detail in the November 22, 1989 Federal Register notice 
(54 FR 58314). In summary, the criteria for inclusion on List 1 
included carcinogenicity, adverse reproductive effects, neurotoxicity 
or other chronic effects, developmental toxicity (birth defects), 
adverse ecological effects or the potential for bioaccumulation. Inert 
ingredients which were placed on List 2 were considered to be 
structurally similar to chemicals known to be toxic or there existed 
data which suggested a basis for concern about the toxicity of the 
chemical.

II. Inert Ingredients no Longer Used in Pesticide Products

    The Agency has identified certain List 1, List 2, and List 3 inert 
ingredients that are no longer used in pesticide products. Many List 1 
inert ingredients are no longer used because of data call-in notices 
issued pursuant to section 3(c)(2)(B) of FIFRA. In response to the 
issuance of data call-in notices (DCIs) for List 1 inert ingredients, 
most registrants of products containing List 1 inert ingredients chose 
to respond to the DCI by canceling the registration or reformulating 
the product to remove the List 1 inert ingredient.
    List 1 inert ingredients which are no longer used in pesticide 
products are identified as follows (with chemical name and Chemical

    According to Agency records, none of the above chemicals have been 
used in any registered pesticide product for over two years, and in 
most cases, the above chemicals have not been used as inert ingredients 
in registered pesticide products for over five years. If a registrant 
disputes the Agency's determination concerning inert ingredients that 
are no longer used in pesticide products and still has an active 
registration for a pesticide product containing one of the chemicals 
identified as no longer used in pesticide products, the registrant 
should immediately notify the Agency as detailed in the ``ADDRESSES'' 
section of this notice. The registrant should include the inert 
ingredient name, CAS Reg. No. for the inert ingredient in question and 
the EPA Registration Number of the pesticide product containing the 
inert ingredient.

III. Policy Governing Future Use of Chemicals that are No Longer 
Permitted for Use as Inert Ingredients

    Because of the toxicological and other concerns associated with 
List 1 and List 2 ingredients, EPA believes that registrants will have 
difficulty proving to the Agency that use of products containing such 
ingredients would not result in unreasonable adverse effects on human 
health and the environment. Therefore, the Agency does not normally 
expect to approve future applications involving the use of any of the 
above List 1 or List 2 chemicals as ingredients, except in those few 
cases where the applicant can clearly demonstrate through the 
submission of data that the proposed use will not adversely affect 
public health or the environment. Data requirements for any such future 
request will be determined by the Agency on a case-by-case basis. Use 
of any of the above List 3 chemicals will be considered by the Agency 
under the same procedures that apply to new inert ingredients specified 
in the April 22, 1987, Inert Inrgredient Policy Statement.

IV. Revocation of Exemptions from the Requirement of a Tolerance 
for Chemicals No Longer Permitted for Use as Inert Ingredients

    The Agency has previously revoked most of the exemptions from the 
requirement of a tolerance for those List 1 inert ingredients 
identified above as no longer used in pesticide products. The Agency 
will propose future revocations of any remaining exemptions from the 
requirement of a tolerance for all chemicals identified above as no 
longer used in pesticide products.

V. List 1 and 2 Inert Ingredients Currently Used in Pesticide 
Products

    There are 8 List 1 inert ingredients and 52 List 2 inert 
ingredients that, according to Agency records, are still used in 
pesticide products. Although the Agency stated in the November 1989 
Federal Register Notice that the List 1 inert ingredient formaldehyde 
was no longer used in pesticide products as an inert ingredient, the 
Agency has now determined that, according to its records, formaldehyde 
is present in some pesticide products as an inert ingredient for use as 
a formulation preservative or as a component of certain proprietary 
mixtures.
     Products containing formaldehyde as an inert ingredient will be 
included in the reregistration process of the active ingredient, 
formaldehyde since the registration standard entitled ``Guidance for 
the Reregistration of Pesticide Products Containing Formaldehyde and 
Paraformaldehyde'' published on May 31, 1988, stated that formaldehyde 
should be categorized as an active ingredient in all products in which 
it is used, including products containing formaldehyde as an inert 
ingredient.
    The remaining List 1 and List 2 inert ingredients are as follows:

VI. Process for Future Removal of Inert Ingredients that are No 
Longer Used as Inert Ingredients

    As a part of its ongoing inerts strategy, the Agency will perform 
future reviews of List 1, List 2, and List 3 inert ingredients to 
identify those inert ingredients which are no longer used. The Agency 
will issue future Federal Register notices removing those chemicals 
from its list of inert ingredients. Any associated exemptions from the 
requirement of a tolerance for such chemicals when used as inert 
ingredients will also be revoked. The Agency will not remove any List 
4A or 4B inert ingredients from its list of inert ingredients since 
sufficient data have been presented to establish that the use of these 
chemicals as inert ingredients will not present a hazard to public 
health or the environment.
    In an effort to identify inert ingredients which are no longer 
used, the Agency may contact registrants of pesticide products or 
manufacturers/suppliers of substances which are used as inert 
ingredients in pesticide formulations which contain specific inert 
ingredients the Agency believes may not actually be in use. This action 
may be necessary to verify the information currently contained in the 
Agency's database relative to product formulation information.
    The Agency considers all alternate formulations valid for purposes 
of registration unless a registrant provides specific written notice to 
the Agency that a particular formulation will no longer be used. 
Therefore, the Agency wants to encourage registrants as part of their 
pesticide product stewardship program to provide the Agency with 
written notice identifying specific formulations that are no longer 
used as part of the pesticide product registration and amendment 
process. This action will assist the Agency in better identifying those 
inert ingredients that are no longer used in pesticide products as well 
as improving the overall accuracy of the Agency's product formulation 
information.
